The present invention relates to a spike for golf shoes consisting of a cylindrical nut installed on the sole of a golf shoe and a spike that is fastened to the nut to generate a ground force to the ground. Specifically, a golf shoe that is easy to fasten and detach the spike from the nut. It's about dragon spikes.

The nut of the present invention is additionally provided with threads so that all of the spikes having fastening means such as bolts or engaging portions can be used.

The nuts and spikes of the present invention are suitably made of synthetic resin.

In the golf green, synthetic resin spikes or spikes have been developed to maintain a stable putting position by generating a grip force with the ground and to give stability when walking on hard ground.

As is well known, spikes for golf shoes are composed of nuts and spikes, and the whole nut is embedded in the sole of the golf shoe, except for one surface thereof, in order to couple the spikes.

As is known, the conventional spike has been mainstream that the nut and the spike is integrated, but the one-piece spike has been pointed out that the rigid coupling of the nut and the spike with different physical properties is a challenge, and poor durability.

However, the necessity of replacement by wear, especially those made of synthetic resins, further increases the necessity of replacement. Therefore, it is generally used that the nut is integrally embedded in the sole of the golf shoe and the spike can be replaced.

For example, a structure for screwing a spike to a nut coupled to the sole of a golf shoe by separating the nut and the spike has been proposed (FIG. 1). However, the screw fastening structure is time-consuming since the spike is rotated a lot and is particularly long-term. If used, the screw may loosen, causing the spike to break out.

Recently, a structure in which a nut and a spike is easily coupled has been proposed. As a representative structure, a coupling portion of the nut is configured in the form of a triangular groove, and the spike coupled to the central portion is configured in the form of a triangular protrusion corresponding to the triangular groove. On the other hand, at the corners of the triangular groove and the triangular projections are provided with a structure in which the fastening projections are fitted into the fastening grooves by only slightly rotating the spikes when the coupling grooves and the fastening protrusions coincide with each other.

However, such a structure has a disadvantage that the coupling means of the spike is somewhat easy, but the manufacturing cost is high, and the problem that the spike is easily separated by a slight impact as a nut and spike is a fitting structure of the groove and the projections.

To solve this problem, as shown in FIGS. 2A and 2B, the inventor of the present invention introduces a nut and a spike that enable the use of both a bolt (screw type) and a spike provided with an engagement portion. (For example, Republic of Korea Utility Model Registration No. 0238321)
